Polyimide Fiber For High Temperature Filtration
Hot air filter bags made of polyimide fiber for high-temperature filtration can be used for a long time at temperatures up to 260°C;
Polyimide fibers for high-temperature filtration are most successfully used in filter cloths in combustion flues, coal furnaces, cement kilns, or asphalt plants. The surface coefficient is larger than other fibers. When the pressure difference is small, the filtration efficiency is very high.
1. Product Introduction
Polyimide fiber for high-temperature filtration has outstanding high-temperature stability, excellent dimensional stability, and chemical stability, and its long-term use temperature can reach 260°C.
Polyimide fiber for high-temperature filtration is often used for high-temperature flue gas dust removal in cement plants, coal-fired power plants, steel plants, waste inineration plants, metal smelting plants, chemical plants, and other industries.
